Ehsan's Growth Analysis
Resend is proof that even in a mature, boring market (transactional email), there is room for a new entrant if the developer experience is dramatically better. SendGrid and Mailgun have been around for 10+ years. Both work. Neither is enjoyable to use. Resend's open-source React Email component library was the Trojan horse — developers adopt it for the beautiful email templates, then discover Resend's API is the easiest way to send them. The $8.5M raise is modest by today's standards, which is actually a strength. Low burn rate + high developer love + inevitable enterprise expansion = a company that can grow into profitability without dilution. The email API market is $4B+ and no incumbent is innovating.
